My Dad lost 6 stone last year on LL.
He lost it over 3 months and then followed the maintenance steps religiously. He has not regained a lb!!!
His diet has competely changed. From copious amounts of red wine, cheese on toast (as a snack), steaks, sausages, crisps, loads of bread. He now eats vast amounts of fruit, salad, veg, lean meats and fish, some red meat and some treats. He now doesnt drink alcohol at all.
He still eats large quantities but of low calorie density foods.
Am very proud of him and it shows that if you do it properly and change your eating habits too then it definately does work!!!
Good luck!
